I am a bit late to reply here, I surprised that you didn't find any book on organometallic, well dont worry dear I suggest some books I hope it will help you, these are
1. Flash Points of Organic and Organometallic Compounds
2. Organometallic Syntheses
3. Preparative Polar Organometallic Chemistry
4. Speciation study of organometallic compounds
These are best books for understanding Organometallic, these are lil bit expensive in local shops, I also bought it from Back to school coupons, at reecoupons, here much discounts are available on educational accessories if you wanna buy once search there hope you will find. You can check my sign for this purpose.
